The long-awaited arrival of Blackberry Messenger seems to be finally here, as Blackberry accidentally released the user guides for BBM for iOS and Android.

Techcrunch reports that for previous BBM users from BlackBerry, most of these details are familiar. The apps are designed to allow for real-time communication between contacts and groups, the guides explain, letting users share pictures and messages, including broadcast messages, multi-person chats, and group chats. Users will also be able to create BBM Groups, where they can plan events, track to-do’s, share photos, and chat with up to 30 people at a time, without the need to add everyone as BBM contacts.

BBM will work over both cellular and Wi-Fi, the latter option which is meant to help avoid data charges when traveling.

Each user can establish their own BBM profile, where they can choose a display picture, name, and status that their contacts will see, and they’ll also have a unique BBM PIN which they can access by tapping “Show Barcode.”

This is a major move for the struggling company, as BBM has for a long time been one of Blackberry, and the BB10′s, strongest features. At launch, Heins had said that only messaging and group features will be available, but promised that the rest of BBM will eventually make its way to the Android and iOS versions including screen sharing, BBM voice, and the newer BBM channels.
